Answer:
<u>6b - 4a + 22 units</u>
Step-by-step explanation:
Perimeter = 2(length + width)
= 2(3b - 4a + 5 + 6 + 2a)
= 2(3b - 2a + 11)
= <u>6b - 4a + 22 units</u>
Step-by-step explanation:
4m =16
divide both sides by 4
m = 4
he has 4 model trains
The sum of interior of all angles in a triangle = 180
Given 3 angles = <span>80°, 2x + 2°, and 5x°
To find x:
</span><span>80°+ 2x + 2 + 5x = 180
7x + 82 = 180
7x = 98
x = 14
answer
x = 14 </span>
